Is there a way to dump the Jasmin ROM, on a disk or on tape?
Godzil asked me to dump mine to check if there are different versions, and I'd prefer a way to do it without opening the drive and dumping the chip.

Good question.
I guess the Jasmin works more or less like the microdisc, with a double rom selection system, one to disable the system rom, and one to enable the Jasmin rom, then it's just a matter of copying the data in lower ram and then save it?

This is the case, and from memory it's a low size ROM (but I can't remmember the size..)

Other solution is to dump it via a classic (E)PROM reader (I have one if needed)

Okay, had opened and dumped the ROM, but it was strictly similar to the file that was with Euphoric.
And now, I just found that the Jasmin manual explains how to access the overlay RAM. Oh well, read the docs first

EDIT: I was tired yesterday I guess... The overlay RAM is not the ROM of the controller card... So dumping it was a good idea after all

I would be surprised if there was any updates to the Jasmin ROM. Unlike the Microdisc, the creators of the Jasmin (sensibly) kept the complexity of the ROM to an absolute minimum. It reads a boot sector and executes it. You can then load the real "ROM" into the overlay RAM, and it means you can fix bugs without having to replace ROM chips.

The Microdisk ROM is also quite simple, the DOS part is nearly not used at all
